Lasers

The hours I spend in the physics and chemistry labs of St. Lawrence University make me a bit inured to the optical shenanigans occurring when we take Raman spectra of the materials my students synthesize. Still, the effect is pretty fantastic. The grainy pattern of the laser on surfaces around lab is fantastic, but the fluorescence ink on the post-it note in the foreground fluorescing aggressively is pretty cool, too.

That violet-blue light in the background of the shot above is the 405 nm laser we use to initiate photochemical processes. The beam is poorly detected by the camera’s sensor, but the slightest hint of it is visible in the upper third of the image below.

Appleton Under Construction

St. Lawrence University is renovating its historic Apple Arena, home of the Skating Saints, and the project is entering its final phases. Back in May, however, the foundations were just being poured and the skeleton of the structure was laid bare. Can you spot the steeple of Gunnison Memorial Chapel on the horizon?

Town Maintenance After Winter

As frozen rain bounces off the roadways of northern New York, I’m reminded that our town works truly do battle with the elements each winter. Floating high over their facilities when spring finally arrives, I feel like I’m looking over the encampment of a victorious army.
